The attached log file shows a properly working Xserver, and Radeon 7000
works fine for me on several machines here, so it isn't clear what the
problem is that you are experiencing without a lot more information,
and detailed steps on how to reproduce.  Can you please provide a detailed
explanation of the problem, and how to reproduce it.

Also try disabling DRI by commenting out the line in the config file which
loads the DRI module.

Correcting incorrect spelling in summary of "readion", changed to correct
spelling of "radeon" so it comes up properly in search queries.

never mind ForcePCIMode worked fine.

Comment 5 Need Real Name 2003-04-27 08:01:45 UTC
Had the same problem described above. Thankfully I found this bug report as 
the 'Option "ForcePCIMode"' addition to XF86Config fixed the problem.

Perhaps this option should be added by default as the only way to successfully 
install with this card that I have found is to use linux expert at cd boot 
time then specify text mode login when configuring with anaconda then editing 
the XF86Config file and changing to gui login again - a real pain.


Comment 6 Mike A. Harris 2003-04-28 12:38:30 UTC
The ForcePCIMode option is an option to begin with because it enables
experimental code which is unsupported and known to create problems for
many people.  It is very hardware dependant, and it is defaulted to OFF
very purposefully.   It is however an option, so that people who need/want
to use it, can.

There is no way to detect when ForcePCIMode can be used safely, and when
it will cause problems, and there is no way to determine what cards might
need it and which ones do not.
